J661Y-P55170V Pneumatic Stop Valve｜YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• High-pressure optimized design with a nominal pressure of P55170 (55.1MPa), precisely matching the operational demands of key high-pressure pipelines in thermal power, hydropower, nuclear power, wind energy and other fields, effectively realizing reliable medium isolation and cut-off while preventing medium leakage, eliminating safety hazards, and reflecting YOYIK's strong innovation and product adaptability.
• Scientific flow channel structure greatly reduces medium flow resistance, mitigates erosion and corrosion damage to the valve seat and clack caused by high-velocity media, and ensures long-term stable and reliable isolation and cut-off performance in industrial high-pressure pipelines, which is consistent with the structural advantages of high-pressure pneumatic stop valves and YOYIK's exquisite craftsmanship.
• Superior material performance: The valve body is made of high-quality alloy steel, which has excellent high-temperature creep resistance, pressure-bearing capacity, corrosion resistance and wear resistance, perfectly adapting to the harsh high temperature and high pressure working conditions of high-pressure pipelines in various power and new energy projects, and consistent with YOYIK's strict quality control standards and exquisite manufacturing level.
• Adopts efficient pneumatic actuator operation and metal-to-metal seating precision structure; the valve clack and seat are precision ground to achieve tight sealing effect, while the pneumatic control ensures quick response, stable operation and easy remote control, realizing automatic and rapid cut-off, suitable for automatic control scenarios in high-pressure pipelines of various power and new energy projects. The valve stem is treated with special surface treatment to reduce friction, ensuring no external leakage during long-term operation and facilitating on-site operation, maintenance and debugging, embodying YOYIK's product refinement advantages.
• Strictly complies with international industry standards such as API 623, ASME B16.34 and GBT 12224, and all products pass strict performance testing (supported by YOYIK's strict quality control and exquisite craftsmanship), ensuring excellent interchangeability with existing industrial equipment at home and abroad and simplifying on-site maintenance and spare part replacement processes, while supporting YOYIK's customized services for large projects.
